well theres very little choke, and ping, mayb theres 1 person with a 120 ping which i dont think will matter, and doubt its not the cpu, im just getting bad registration, and people complaining of lagg

Can you check the FPS when they say it "lags"?
Also I don't see anything wrong with the rates at all...
Low memory can decrease registering of shots too.

Exutable:

If calculated on a 100 tick server for 16 players every slot will use around 18KB/s, so lets say max of 25KB/s at at ultra peek times (very rare if it happens at all, also limited by 25000 maxrate = 25KB/s per player).
25 * 8 = 200 (to go from BYTES to BITS)
200 * 16 = 3200 = 3.2mbit
